Benefits of technology

The present invention motor has second magnetic members arranged in a V shape, which reduces the likelihood of magnetic saturation and allows for higher rotational speed. The rotor core is also stronger, making it can withstand higher stress and rotational speed without deformation.

Problems solved by technology

This will cause the loss of magnetic lines of force and affects the efficiency of the motor.

Embodiment Construction

ss="d_n">[0025]Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0026]As shown in FIG. 1, a motor according to an embodiment of the present invention comprises a rotor core (1) and a stator core (2). The rotor core (1) has a plurality of spoke-type first magnetic members (11) that are arranged radially around the periphery of the rotor core (1). Two oblique second magnetic members (12) are provided between every adjacent two of the first magnetic members (11). The two second magnetic members (12) are arranged in a Vshape relative to the center of the rotor core (1). Every adjacent two of the first magnetic members (11) and the two second magnetic members (12) jointly surround an area (A). The first magnetic members (11) and the second magnetic members (12) face the area (A) with the same magnetic pole. The stator core (2) covers the rotor core (1). The stator core (2) has a plurality of stator windings (2...

Abstract

A motor and a spoke-type rotor structure thereof are disclosed. The rotor structure comprises a rotor core which has a plurality of spoke-type first magnetic members. Two oblique second magnetic members arranged in a V shape are provided between every adjacent two of the first magnetic members. A radius of the rotor core is R. A length of the first magnetic member is ls. A length of the second magnetic member is lv. A length component of the second magnetic member on the radius of the rotor core is x. An included angle between the first magnetic member and the second magnetic member is β. An included angle between every adjacent two of the first magnetic members is α. The parameters satisfy:ls+x<R, wherein x=lv·cos(180°−β);90°+α / 2<β<180°.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a motor and a spoke-type rotor structure thereof, and more particularly to a rotor core having two oblique second magnetic members arranged in a V shape relative to the rotor core and located between every adjacent two of spoke-type first magnetic members.BACKGROUND OF THE INVENTION[0002]Referring to FIG. 6, a conventional motor structure comprises a rotor (A) and a corresponding stator (B). The rotor (A) has a plurality of magnetic members (A1) arranged annularly. The stator (B) has a plurality of stator windings (B1) corresponding to the magnetic members (A1). When the motor runs, the magnetic lines of force generated by the magnetic members (A1) of the rotor (A) are partially directed to the inside of the rotor (A). This will cause the loss of magnetic lines of force and affects the efficiency of the motor.[0003]In order to improve the above problem, another conventional motor structure as shown in FIG. 7 is developed, ...
